New rock with some hitchhikers, how do I care for them?

[Verruckt]

I bought this rock, they gave it to me for the per/lb live rock price so I thought it was a good deal considering whats on it.

These guys seemed beautiful and stretched out when first put in my tank. I have a Coralife with a 96 watt Actinic and white 10,000K quad bulb. Is that enough light? The rock is sort of up hight, maybe 4" below the water line. Surely they are not burning up??? Food, what they hell do I feed these guys?? I hope I didnt screw this up. :?

So I guess my questions are...
a) what are they
b) am I providing them enough light
c) what should I be feeding these guys[/img]

The green one looks like a mushroom (kind of hard to tell for sure), and the others some sort of zoanthid polyps. That red thing on the corner looks like a sponge, but it's pretty hard to say. Assuming my IDs are correct, they're pretty easy to take care of. You don't have to feed them anything, and your lighting is sufficient. Just keep up on your water changes, and they should do just fine.

Verry, if the sponge was taken out of the water at all it's likely that it's going to die. Be prepared with plenty of water for water changes. The green thing is indeed a mushie. The zoas should do fine, as should the mushie as long as your parameters are good. Where was the rock located in the shop's tanks? You can indeed burn them if they haven't been exposed to such bright light before (where collected is also an issue, but few people know at what depth the rock was, etc.).

The rock looks to be VERRY precariously perched, be careful with that!

Nah Sea, this was in one of their tanks. The guy was just cuttin me a deal since i was buyin a bunch of other crap. So these are entirely "tank raised"

Mushies are generally not a high-lumen/high light intensity requiring group of inverts. As I said, if the sponge came out of the water, the air trapped in its tissues will usually kill it. They can usually tolerate having the bad tissue cut away, but I am absolutely not an expert on sponge care.

Other than that, water parameters and if your lighting is much brighter than the shops then there are a few ways to acclimate the zoas to the new light. You can move the lights up, you can block with some glass, you can move the rock down.

If that's the type of sponge I think it is (assuming it's a sponge at all), I have a bunch in my tank, and they don't seem to have any particular care requirements. It looks pretty small, though, so even if it dies, it's not going to cause any problems.
